Should I start blogging in some form
Sure, go for it.
Only in a particular form (see question 2).
Eh, maybe, up to you.
Probably a bad idea because it's a waste of time and effort.
Probably a bad idea because you risk future employment prospects or may have to shut it down if you get a government job.
What naming or organization should I go for
Eponymous. Since you're doing this under your own name, why complicate things.
Try to set up a group blog with some friends, starting out alone is tricky.
Go for a neologism, though possibly a less evil one than Synerdigm
Go for an existing word or phrase that's relevant to your content.
Don't start your own site, things are oversaturated, just try to post on existing ones until you get a regular gig.
Topics for my global strategy institute post
Rise of private military contractors (mercs).
Globalization and inequality.
Something on trends in global conflict.
Quick version of the paper I'm doing on the advantages of standardization over integration for software.

I'd also be interested if people have any suggestions regarding which blogging software to use.
